lThe saurereferenee numerals denote the -is i'fegards'in the tti-st pla-re the example shown in Figs. 1 to 1, the reference numerals 1,' 2 denote two toothed sertors, one of which is vfixed to the handle 3 and the other to the loom 4 of the oar. in this example the seetor .1. is ofvsnia-ller radius than the sector 2: but the reverse maybe the ease, the ratio between the radii varying aeoordino to the ease. The two toothed sectors are held between two plates 5 and 6 by means of pins 7, S, around which they are able to pivot:

the lower plate 6 has two lugs 9: a s indle- 10 sen-*info*l as axle passes through ori ees in said lugs and through those in llugs 11 of a base plate 12 whieh is suitably fixed. on the gunwale of the boat. 4ln this way the combination of the toothed sectors and of the plaies vis setured to the gunwale and can pivot around the spindle 1() turning the oar therewith. I have found rthat if the plate 12l be simply serewed to the gunwale lthere is a Iris-k of linjuring it, the

are therefore added two like stirrup-pieees 13 the ends of which enter dove-tailed mortses 14 formed in. the platefll?. rThese stirlfup pieces bear aga-inst the edge of the boat, one

.in the interior and the other on the exterior and are serured by ybolts provided with nuts 15. The si irrup piet-es play at the saine time.

'chape 20 Carried by the effort not. being spread over a large enoughsurface. There `30 the blow of pin 7. lt is surrounded by a coil spring 21 which abuts against the collar 22 on the rod 19 and against a washer 23 supported by the chape 17. The lower part of the rod 19 is .5 screw-threaded and entersthe regulating nut and j ani-nut 24. The oar may dip until thenutabuts against the chape 17 but it cannot dip farther, the handle being retained bygthe rod 19 jointed to the pin 7. To restore the oar to horizontal position it suihces to press on the wrist, the rod being then lowered and compressing the spring 21. -On theloom lof the oar there .'may be distance marks: in this way it can be immediately seen how far the i5 oar has dipped, and the dip of each oar may be regulated. The di may also be indicated on the interior of the kiff by indicator pointers. The outer stirrup piece 13 carries also the means for causing the blade tol turn 20 through an angle of 90 at the end of its movement for feathering. Two slide blocks are solid with the two branches ofthe stirru 13 and two rods 26, 27 can slide in said b ocks and can also telescope one` Within 25 the other. The blocks 25 carry set screws 2S which enable the rods to be locked at the desired position. The rods each carry a stop pin 29 per endicular to their direction. The feat ering of the blade is eHected lby a small rod 30 carried by the loom 31 against one of the stop pins 29. The loom 31 is mounted on ball bearings in the socket portion 4 which is perforated to allow for the passage'f the rod 30. rVhen 3,5 this rod has struck/against one of the. stop ins and thereby eHected one-half of the eathering movement this movement is completed by a spring 32 which is compressed duringytheirst half of said movement and thereafter expands the rod thus turns around 90 carrying with it theloom 31 and the blade which is alixed to its extremity. It will be observed that the rotations oi` the r blade in one direction or the other in order to bring the blade into vertical or horizontal position are produced after an angular displacement toward the front or the rear the extent of which depends upon the distance between the stop pins 29; this movement can 50 thus be regulated by changing this distance and 'for this purpose it suffices to slide the rods 2 6 in the blocks 25 after having unlocked the screws 28: said screws may be locked again after the adjustment. Supplemental stops, which may be elastic er not, may be employed to stop the oar at the end et its forward and rearward movements diirrp/shout straining the rod 30. The oar shown n Figs. 5 to 7 com rises elastic stops oi this kind as will be seen ater.

The loom 31 which carries the blade may, 1f desired, be constituted of several sections capable of telescopin one within the other so as to permit the'a justment of the length according to circumstances.

- the stirrup pieces.

The blade 33 which is at the end of the loom 31 mayv be of wood Or metal, and as above stated one feature of the invention f consists in the application of a blade provided with a large number oi' small holes.

When the blade is of sheet metal it is strengthened by ribs which may be either pinnated or palmatcd longitudinal parallel, etc. but preferably comprise a central longitudinal rib and a series of supplementary ribs extending outward audiorward therefrom, as shown in Fig. 2.

In the example shown in Figs. 5 to 7 the sector 1 of the handle is represented as oi' larger radius than the sector 2 of the-loonr In this case the dip is limited and regulated by means ol' an external track 347 the inclination oi which may be varied at will anden which the loom of the oar rests by the inter media-ry ol' a roller 35 with which it is provided. The track 34 is carried by two arms 36 which are able to turn around the axis 37 carried bythe plate 12. One of the arms 3G is prolonged by a lever 38 at the other side of the pivot 37. The lever 38 terminates in an eye 39 of elongated form. Through this eye passes a screw,40`jointed at 41 to a lug in the late 12. Above the lever is a nut 42. 0n

is lowered and in consequence the arms 36 and the track 34 are raised. The inclination of the oar is thus altered. Likewise by raising the nut 42 the oar is permitted to dip farther'. On the other hand, nothing hinders the oar from being raised to horizontal position. In the arrangement first described the loom 31 turned with the blade: in this case the loom is rigidly fixed to the socket 4 of the blade and the blade may turn through along its longitudinal axis: to this end it is provided with a tail 43 which'is mounted on ball bearings in the hollow loom 31: the rod 30 is connected to this tail by a rod 44 which passes along the axis o1" the loom 31. In this instance the distance be tween the abutments 29 can not be regulated; these abutments are solid with the track 34 which carries besides the spring buffers 45 sto s against which the socket 4 abuts at the en of its movement so as to limit the extent of the movement of the oar without 'straining the reversing rod 30 The construction shown in Figs. 8 to 11 only diflers from that illustrated in Figs. 1 to 4 in respect of the details of construction. In this construction the plate 12 is in one piece not only with the sup orting brackets 11 of the oar vbut also with t 1e stirrup pieces 13: further the chape 17 is solid with one of Besides, the axis of oscillation 10 1s .in one ieee with the plate 6 and is maintained in tlie brackets 11 by caps 46 which are jointed at 47' to projections 48 on the lplate 12. By means oi this arrangement it is easy to remove the oar ai'terlowerowering the nut on the screw 40 the lever 3S lill',

l Wish it to be understood that the details of construction illustrated and described are only given by way of example and that thc various parts which constitute the apparatus described may be combined in any manner or employed separately.

Having now described my invention whatl l claim and desire to secure by Letters Vl3ntent oi the United States isz-- l. The combination with a fixed base plato and an oar mounted thereon to oscillatc on a horizontal axis, of means for controlling the dip ol' the oar blade comprising a rod which ing movement at it-s other end,`said rod being provided u'ithan adjustable abutment ser-ving as a stop l'or limit-ing its sliding-1novement and thereby determining the maxi muni inclination of the oar.
